A5.0-kg hollow cylinder of radius 0.37m rotates freely about an axle that runs through its center and along its long axis. a cord is wrapped around the cylinder and is pulled straight from the cylinder with a steady tensile force of 50 n . as the cord unwinds, the cylinder rotates, with no slippage between cord and cylinder.
a- calculate the work done by the tensile force as the cylinder rotates through 1000 rad
b- if the cylinder starts from rest, calculate its rotational speed after it has rotated through 1000 rad .
